It's enough to create a waveofquestions about whether a college education is still worth it.

A new set of income statistics answers those questions quite clearly: Yes, college is worth it, and it's not even close. For all the struggles that many young college graduates face, a four-year degree has probably never been more valuable.

The pay gap between college graduates and everyone else reached a record high last year, according to the new data, which is based on an analysis of Labor Department statistics by the Economic Policy Institute in Washington. Americans with four-year college degrees made 98 percent more an hour on average in 2013 than people without a degree. That's up from 89 percent five years earlier, 85 percent a decade earlier and 64 percent in the early 1980s.
